Sensor Board

sensor board

The Complex Arts Sensor Board is an inexpensive, robust solution for motion detection.
The Sensor Board features the BNO085 IMU with an ESP32 WROOM microcontroller,
enabling a large range of applications including gesture sensing and vehicle control.


The Sensor Board combines the versatility of the ESP32 series microcontroller with the precision of the BNO085 motion processing unit.
It can act as a stand-alone microcontroller, or an I2C slave device (pull-up resistors required).
